PROBLEM TO BE SOLVED: To discriminate the movement of a moving body from a signal including various kinds of disturbance with higher accuracy.SOLUTION: A discrimination device includes: a feature amount calculation section for calculating feature amount of the movement of a moving body on the basis of a sensor signal indicating the movement of the moving body detected by a sensor; an evaluation value calculation section for calculating an evaluation value corresponding to the movement of the moving body according to the feature amount of the movement of the moving body calculated by the feature amount calculation section using a recurrence learning model generated on the basis of a plurality of pieces of data in which the feature amount of a prescribed movement and an evaluation value corresponding to the prescribed movement are made as a pair; and an adjustment section for adjusting a threshold compared with the evaluation value corresponding to the movement of the moving body to discriminate the movement of the moving body.SELECTED DRAWING: Figure 1【課題】様々な外乱を含む信号からより高精度で動体の動きを判別すること。【解決手段】センサにより検出された動体の動きを示すセンサ信号に基づいて、上記動体の動きの特徴量を算出する特徴量算出部と、所定の動きの特徴量と、上記所定の動きに対応する評価値とを組とする複数のデータに基づいて生成された回帰学習モデルを用いて、上記特徴量算出部により算出された上記動体の動きの特徴量に応じて、上記動体の動きに対応する評価値を算出する評価値算出部と、上記動体の動きの判別のために上記動体の動きに対応する上記評価値と比較される閾値を調整する調整部と、を備える判別装置を提供する。【選択図】図1
